Recently, the team of Li Mingqiang, associate professor of Dalian University of Technology, made a breakthrough in green power batteries, which increased the cycle life of nickel-zinc batteries by 10 times
.
The results were published in Nature
.
As a power battery, nickel-zinc batteries have many advantages, especially the characteristics of safety and environmental protection, which are most suitable for driving electric buses
.
However, the current commercial nickel-zinc battery generally has the problem of short cycle life, and the cycle life rarely exceeds 1000 times, which greatly limits its application
in electric vehicles.
Li Mingqiang's team cooperated with Zhang Xiaoliang, an associate professor at the university, to construct a new nickel-zinc battery anode material by using the in-situ cutting technology of zinc oxide to graphene, which was applied to secondary
batteries.
The cycle life of the battery can reach 10,000 times, the capacity attenuation rate is only 0.
0011%, and the maximum discharge capacity is 2603mAh/g, which effectively solves the problem of low cycle life of the negative electrode of nickel-zinc battery, and has a major improvement
compared with the literature.
